        RE: PLAN  AND  AGREEMENT  OF MERGER AMONG HEALTHSOUTH CORPORATION, FIELD
            ACQUISITION CORPORATION AND NATIONAL SURGERY CENTERS, INC.

Gentlemen:

     We have acted as counsel to HEALTHSOUTH CORPORATION, a Delaware corporation
("HEALTHSOUTH"),  in connection with the proposed merger (the "Merger") of Field
Acquisition Corporation,  a Delaware corporation ("Subsidiary") and wholly-owned
subsidiary of  HEALTHSOUTH,  with and into  National  Surgery  Centers,  Inc., a
Delaware corporation ("NSC"), pursuant to the terms of the Plan and Agreement of
Merger,  dated  as of  May  5,  1998  (the  "Plan  of  Merger"),  by  and  among
HEALTHSOUTH,  Subsidiary  and NSC,  as  described  in more detail in the Plan of
Merger  and in the  Registration  Statement  on Form  S-4  (Commission  File No.
333-___) to be filed by HEALTHSOUTH with the Securities and Exchange Commission,
as amended (the  "Registration  Statement").  This opinion is being  provided in
satisfaction  of the  conditions  set  forth in  Section  9.2(c)  of the Plan of
Merger.  All capitalized  terms,  unless otherwise  specified,  have the meaning
assigned to them in the Registration Statement.

     In  connection  with this  opinion,  we have examined and are familiar with
originals or copies,  certified or otherwise identified to our satisfaction,  of
(i) the Plan of Merger,  (ii) the Registration  Statement,  and (iii) such other
documents as we have deemed  necessary or  appropriate  in order to enable us to
render the opinion below. In our examination, we have assumed the genuineness of
all signatures,  the legal capacity of all natural persons,  the authenticity of
all documents submitted to us as originals, the conformity to original documents
of all documents  submitted to us as certified,  conformed or photostatic copies
and the  authenticity of the originals of such copies.  In rendering the opinion
set forth  below,  we have  relied  upon  certain  written  representations  and
covenants  of  HEALTHSOUTH,  Subsidiary,  and NSC which are annexed  hereto (the
"Representations and Warranties").

     In rendering our opinion,  we have considered the applicable  provisions of
the  Internal   Revenue  Code  of  1986,  as  amended  (the  "Code"),   Treasury
Regulations,  pertinent  judicial  authorities,   interpretive  rulings  of  the
Internal  Revenue  Service  and such  other  authorities  as we have  considered
relevant.

     Based upon and  subject  to the  foregoing  and  assuming  that,  as of the
Effective  Time of the Merger and  following the Merger there will be no acts or
omissions which will violate or be inconsistent with any of the  Representations
and Warranties, we are of the opinion that:

       (i)  Provided  the  Merger  qualifies  as a  statutory  merger  under the
    Delaware   General   Corporation   Law,   the  Merger  will   constitute   a
    reorganization  within  the  meaning  of  Section  368(a) of the  Code,  and
    HEALTHSOUTH, Subsidiary and NSC will each be a "party to the reorganization"
    within the meaning of Section 368(b) of the Code;

       (ii) No gain or loss will be recognized by HEALTHSOUTH, Subsidiary or NSC
     as a result of the Merger;

       (iii)  No gain  or loss  will be  recognized  by an NSC  stockholder  who
      receives  solely  shares of  HEALTHSOUTH  Common Stock in exchange for NSC
      Common Stock;

       (iv) The  receipt  of cash by an NSC  stockholder  in lieu of  fractional
     shares of  HEALTHSOUTH  Common  Stock will be treated as if the  fractional
     shares were  distributed  as part of the exchange and then were redeemed by
     HEALTHSOUTH.  These  payments  will be treated as having  been  received as
     distributions  in full  payment  in  exchange  for the  stock  redeemed  as
     provided in Section  302(a) of the Code,  provided  the  redemption  is not
     essentially equivalent to a dividend;



       (v) The  aggregate  tax basis of the shares of  HEALTHSOUTH  Common Stock
    received by an NSC  stockholder  will be equal to the aggregate tax basis of
    the NSC Common Stock exchanged therefor,  excluding any basis allocable to a
    fractional share of Common Stock for which cash is received; and

       (vi) The  holding  period  of the  shares  of  HEALTHSOUTH  Common  Stock
     received by an NSC  stockholder  will include the holding period or periods
     of the NSC Common Stock  exchanged  therefor,  provided that the NSC Common
     Stock is held as a capital  asset within the meaning of Section 1221 of the
     Code at the Effective Time of the Merger.

     Except  as  set  forth  above,   we  express  no  opinion  as  to  the  tax
consequences,  whether  federal,  state,  local or foreign,  to any party to the
Merger or of any transactions  related to the Merger or contemplated by the Plan
of Merger.

     We hereby  consent to the  reference  to our Firm under the heading  "Legal
Matters" in the Prospectuses  which form a part of the  Registration  Statement,
and to the filing of this opinion as an Exhibit thereto.

                                        Very truly yours,

                                       /s/ Robert D. Shattuck, Jr.
